We
set out to make the best spearguns possible for our personal
use. Building on designs of innovators such as Steve
Alexander and Larry Heinrich,
we have developed a line of spearguns that shoot long
range shots very accurately with reduced recoil. We like
these spearguns so much (and so do our friends who have
them) that we've decided to make them available to other
divers. We like to encourage do-it-yourselfers and many
of the spearfishers we know are, so we plan to add to
this website all instructions and dimensions for everything
we make, so you can do-it-yourself if you have more time
than money. These sections are marked DIY.
If you'd like help in selecting the right gun for your
type of spearfishing, check out the article Choosing
The Appropriate Speargun. Note we use the Imperial
system of measurement, but there is a metric conversion
chart at the very end of this web page with conversions
for most of the sizes listed here.
This web site is our only catalogue. We have no other
brochures yet we get many requests for them, but since
we are constantly adding information to this site, we
don't have plans of printing brochures that would soon
be out of date. After all, we are ``Internet Custom Spearguns.''
Just print this main page if you want something on paper
for your reference.
Our
guns and how they're made
The classic open-track, light-weight hardwood speargun
works fine with light shafts of 1/4" or 9/32" diameter
and one or two power bands as long as you use the single
flopper tip (often called a Tahitian or Hawaiian shaft).
But many divers want a longer range shot or more penetration
power, so they may take a classic speargun and add more
power bands, but this only harms the accuracy of these
spearguns. Accuracy suffers for two reasons: 1) there
is more recoil which kicks the front of the speargun upward
which pushes the rear of the shaft up knocking the shaft
off course and 2) the shaft actually flexes (in front
of the fin tabs and behind the spear tip) from the extreme
power applied when the trigger is
released causing the shaft to lose power and accuracy.
This flexing, often called "shaft whip," occurs with as
few as three power bands. Divers try to "fix" this problem
by adding side stocks, sometimes called "wings", which
does help reduce recoil but only enclosed track can eliminate
shaft whip. Another factor that will harm accuracy is
use of a spear tip that is too heavy and bulky for a light
shaft. We also make light, low-profile slip-tips (inspired
by those made by Steve Alexander) to prevent this.
We decided to build spearguns that were designed properly
for long range accurate shots right out of the box. These
spearguns can also carry our threaded slip-tips without
noticeable harm to the shot range or accuracy.
Note that it is so difficult to retrofit an open track gun
with an enclosed track that the effort involved would cost
more than well designed enclosed track gun. If you want
to try it yourself, go ahead, but please don't ask us to
do so. We would rather make a new well-designed gun from
scratch than try to retrofit an enclosed track in a poorly
designed underballasted, open-track speargun.
We start with hand-selected hardwood (usually Teak) with
very straight grain or with many vertical laminations to
prevent warping. Each stock is aged at least two months
after gross cutting to allow it to stabilize, then it is
precision straightened. We cut our speargun blocks very
thick to provide buoyancy to compensate for the mass we
add (via lead) to achieve a speargun with high inertial
mass yet with balance at the handle while in the water.
We precision machine an enclosed track (to prevent shaft
whip). Our Deluxe spearguns are then ballasted with lead
alloys until the speargun is balanced at the handle yielding
a speargun that is balanced yet heavy enough to greatly
reduce recoil. The recoil and shaft whip are primary factors
causing inaccurate shots. Adding side-stocks can reduce
recoil, but only an enclosed track can eliminate shaft whip.
We believe so strongly in enclosed track that we don't intend
to make any open track spearguns. Shooting an under-ballasted,
open track speargun is like shooting a slingshot. Shooting
a ballasted, enclosed track speargun is like shooting a
22 caliber rifle - deadly accurate with low recoil. A balanced
speargun is so comfortable to use it is a delight to dive
with and as far as we know, no one else is selling balanced
spearguns.
One
pioneering innovation is the use of a solid round rod made
from a space age plastic, called Delrin,
that is as slick as Teflon yet very tough. We use a
solid Delrin rod which is inserted into a track we machine
into the hardwood block. It is then pinned in place with
stainless steel pins. We use a specially developed method
to eliminate expansion stresses due to the differences in
expansion rates bewteen Delrin and wood. The enclosed track
is then machined into the Delrin yielding a track that is
extremely slick and tough plus it won't swell in water as
wood-only enclosed tracks can. This designed was pioneered
by Bill Kitto. The Delrin is
dense and it also contributes to speargun ballast. This
makes the hottest speargun available at any price. The Delrin
insert is available for a $200 surcharge (which covers the
cost of the Delrin and the cost of machining the track for
and pinning the Delrin), but it is well worth it - so much
so, that we encourage anyone who is searching for the best
speargun money can buy to get this option. A wood enclosed
track can swell and pinch the shaft and may eventually wear-out
becomming loose with use - particularly if used around sandy
water, whereas the Delrin is extremely durable and does
not suffer from either of these problems. We normally use
black Delrin, but we made one speargun with white Delrin
for better contrast to show more detail. We can at your
request and have used other other insert material such as
delrin/teflon mix, teflon, and the very expensive PEEK.

An innovation we are currently working on is the replacement
of delrin with a cast in 2-part specially formulated polymer.
This polymer has a greater density than delrin so it will
add mass to your gun and it does not expand or contract
with varying temperatures so it will impart a great addition
of strength to your gun.

Have you ever had an
idea about how your spearfishing gear could be improved?
Ever thought of actually making your own improved parts
or equipment but were disheartened because you thought it
would be too difficult or too expensive?
Well now you can turn your spearfishing ideas from fantasy
into reality for a VERY affordable price.

Workshop.
We
feel our spearguns represent value. If you take a classic
speargun and add side stocks, you may pay $1000 (or more)
yet you may still have problems with shaft whip and the
balance is likely to be incorrect. It is extrememly difficult
to add an enclosed track to an already made open-track gun,
and we won't even do it, because it is far easier to make
a new gun from scratch. (Plus the speargun block needs to
be perfectly straight to machine the enclosed track.)
Range
and Prices
Our
Basic models are price competitive with mass-market designs
that lack the innovations such as enclosed track and ballasting,
plus you'll find our wood stocks are much more substantial
than those of our competitors. Our spearguns also come with
a more durable epoxy finish (instead of Tung oil that washes
out after a few dive trips) so they look nice longer. You
may outgrow the classic speargun and go searching for a
better speargun later (spending much more in the long run)
but you will not out-grow our spearguns. Picture of gun
rear view with reel.
Our Deluxe models are `fully-loaded' with Delrin insert,
appropriate size of side stocks, muzzle stablizers, and
full gun ballasting and balancing. These are the spearguns
we use and recommend. You can get them finished or unfinished.
The Unfinished Deluxe models are by far the most popular.
Our Basic models are fully-rigged, wood enclosed track,
finished spearguns that are still superior to other spearguns
on the market. Basic models are not ballasted or balanced
because they lack the side-stocks necessary for attaching
ballast. We also offer a Partial
Speargun Kit for do-it-yourselfers who don't have access
to a machine shop, but can do other wood work.
We provide everything you need for spearfishing including
spearguns, spear tips, side stocks, float lines, bungies,
big game floats, speargun rigging, machining tools, and
other accessories.
We continue to do research and testing to perfect the design
and components used for all aspects of spearfishing. We
have perfected the powerband gun and are exploring variable
hi-power pneumatic guns and innovative cocking assist devices
using rare earth magnets.
Summary of Speargun Features
-
We use the best components available including beefy
hardwood gun blocks. Multiple ply vertically laminated
stocks are available as an option for $50 more, but
we may substitute them anyway at no extra charge if
we can't find enough ideal solid wood.
-
Enclosed track for shaft - contributing to more accurate
shots by preventing shaft whip
-
Handle is located forward from the butt as is necessary
for proper balance and more stable two-handed shots.
Handle location is customizable, but we won't even consider
placing the handle at the rear. A rear-mounted handle
yields a speargun that can not be balanced and thus
is very uncomfortable and awkward while diving. Ideal
handle placement depends on the length of the diver's
fore arm. Proper fit is when you hold the handle in
your hand with elbow bent, the butt should fit firmly
against your bicep. This allows optimal range of movement
and proper bracing with other hand. An inch longer or
shorter is fine, but much shorter and you can not achieve
proper speargun balance at the handle. Much longer and
you lose ease of mobility and risk serious dental or
face injury - particularly on under-ballasted spearguns.
-
Rear-located trigger mechanism - for maximal band stretch
and maximum power yet not so far back as to become difficult
to load. We feel the ideal placement is where the rear-most
fin tab is at least 6 inches forward from the speargun
butt. However, we will put the mechanism wherever you
like.
-
Four (or more) power bands - for high power, long-range
shots.
-
Our Deluxe spearguns are ballasted so you can shoot
them one handed with a bent elbow (if you like) and
you will not get hurt from recoil - even on our largest
models.
-
All spearguns float with the shaft out - to reduce chance
of losing speargun while fighting a fish (although you
should put your left arm through the power bands while
fighting the fish to avoid losing it anyway).
-
All spearguns come rigged with power bands, threaded
shaft, and monofilament shooting line. Spear tips are
not included. For monofilament we usually use 300 lb
test line for 5/16" shafts and 500 lb test line for
3/8" shafts, but you may choose any from 300, 400, or
500 lb test. You may substitute 500 lb test coated 49
strand stainless steel shooting line for an extra $10,
but note this will reduce the range and accuracy of
your shot - more so on the lighter shafts than with
the heavier shafts.
-
Guns typically have about 4 inches of shaft overhang
(extending over the end of the speargun muzzle) without
tip, so with a 5 inch tip, they will have 9 inches of
shaft overhang. This is also customizable if you prefer
more or less shaft overhang. It is a myth that you need
lots of shaft overhang for sighting. If a speargun shoots
where you aim it, you don't need it. Some find extra
shaft overhang aids in aiming a speargun that shoots
low (or lobs the shaft to the target). Too much overhang
yields a speargun that is also difficult to balance
unless you add side stocks that extend well in front
of the handle. Pool tests indicate excessive shaft overhang
contributes to loss of accuracy on a high powered speargun
by allowing the shaft to whip.
-
All Deluxe spearguns are balanced for a specific shaft
and spear tip combination. Commitment to a specific
shaft and spear tip combination is critical to achieve
proper speargun balance. If you plan to use different
weight spear tips, we balance with the lightest then
the speargun becomes slightly muzzle heavy when you
use one of your heavier spear tips which is preferable
to a speargun that is too light in the muzzle.

The M6
Kitto's newest trigger mechanism is now available.
The new mechanism is extremely robust and stamped on
heavy duty stamping presses from 13 guage 304 SS. The
internal parts are the Kalohi design (see below) with
an optional safety. The sear and 2nd member are made
from heat treated 17-4 SS.
Prices for mechanism only:
1-5 mechanisms: $65/each
6-10 mechanisms: $60/each
11-19 mechanisms: $55/each
20+ mechanisms: $50/each
- The
M5
This ground-greaking innovation gives divers
maximum performance out of their gun with virtually
no 'over-cock' of the trigger.
It works using a two-stage cocking process:
1.
You push the shaft in from the fired position
until it is half-cocked. This will hold the shaft
in place as the sear is about half-way up the
notch in the shaft. |
2.
Then you pull the orange loop. This pulls the
intermediate lever like a crow-bar which in-turn
drags the sear with it until the intermediate
lever latchs on the trigger and stops in this
position. This will guarentee virtually no-overcock
of the sear --- thus positioning it as high as
possible in the notch of the shaft. |
Testing
has shown that this last "little bit" is crucial
in the performance of the mechanism. 50
thousanths of an inch difference in the notch engagement
means approximately 1,000 lbs of force potential on
system. I raised the top of the sear by 40 thousanths
of an inch in the final configuration of the M4 and
it went from consitant failure at 2,100 lbs to 2,700
lbs in the next test, wherein the carabiner holding
the system in failed --- upon removal
of the parts from the M5 under test, there was no noticable
damage at 2,700 lbs.
-
The M4 - Kalohi
The M4 is the 3 part design of Joe Kalohi. When Joe
and I first discovered the solution to the trigger pull
problem exhibited by 2-part mechanisms with high band
load, we agreed it was a simple concept called 'nested
levers'. However, our 3-part designs took separate paths
from the beginning. Joe's - pictured here - has the
two-spring member as the trigger. Mine - the M3 below
- has the mid-part-lever with both springs. My design
has the advantage of much more leverage - the mid part
lever of the M3 is quite a bit longer than that of the
M4. But the M4 allows for a sear operated side line
release that is not available with the M3. The M4 exhibits
no noticable trigger pull increase up through 1250lbs
on the system. We soon will have a comparison chart
with all the leading triggers and their trigger-pulls
vs shaft load informating, also their fail points.
Trigger
pull info for the M4 is as follows:
500 lbs: 1 lb 6 oz
750 lbs: 1 lb 14 on
1000 lbs: 3 lb 2 oz
1250 lbs: 2 lb 14 oz
PRICE: $132, includes line release
Mounting fee: $120

Millenium 3 trigger mechanism *patent

This new model is as far ahead of the typical 2-part
design and the 2 part was ahead of the original 1-part
design. Composed of 3 nested levers with unique cocking
links and a remote activating lever - it specs out to
give about 2 or 3 pounds of trigger pull with around
1400 lbs of force on the shaft -- mainly for tuna guns
with extreme range and shaft sizes (13/32 and 7/16 shafts).
The Millenium 3 mechanism, pictured below, retails at
$135/unit and is available now. E-mail
us for more information or to place an order.

2 trigger mechanism *patent

 |
 |
The little sister of the Millenium 3 trigger mechanism,
the Millenium 2 is a two-part mechanism designed to
replace and improve upon other mechanisms such as Wrife,
Alexander, and even our original Millenium mechanism..
It uses the same sear as the Millenium 3 which is stroger
than the old Millenium sear. Its larger and most importantly
has a much stronger pivot pin - 1/4 inch in diameter
as opposed to the Millenium's 3/16. You won't find a
larger pivot pin in any other competitor's mechanism.
All the forces on the trigger mechanism gets concentrated
on this heavy-duty sear pivot pin. The Millenium 2 also
shares the Millenium 3's 'remote trigger' design.
The Millenium 2 model retails for $85 - an associated
line release and allen screw retails for $12. Our mechanism
is the best you can buy (by far), but we will substitute
the Alexander mechanism which is also very good, if
you prefer, for the difference in our cost ($75 more).
Our mechanism internals are pictured above.
If you would like to upgrade your current mechanism,
we offer free installation of our Millennium 2 mechanism
(when you purchase the mechanism directly from us) into
any speargun built by Internet Custom Speargun as long
as you provide transportation to and from our shop.

Mechanism Testing
In this section we show how to construct an accurate
tensile testing jig and the results of testing a variety
of trigger mechanisms.
-
Our spearguns shoot standard shafts made by Alexander
or a major manufacturer (whose name rhymes with "life"
although some think it rhymes with "jiffy" and we will
spell it "Wrife" so we don't use their trademarked name
without permission) so replacement shafts are available
at dive shops world-wide. These shafts have power band
fins resembling shark fins and the front fin has a hole
for attaching the shooting line. Shooting line is usually
attached to the shaft fin, but you can substitute a
slide ring for an extra $10.
-
We usually "open up" the last 4 inches of the enclosed
track (towards the tip) to allow for easier reloading
without harming shooting accuracy. If you prefer, we
can leave the entire track enclosed.
-
Epoxy sealer finish with Tung oil top coat - for a durable
finish that is protected from UV sunlight. An extremely
durable ultra-high-gloss Polyurathane top coating finish
over the Epoxy sealer with 5 year guarantee is available
for $200 more.
-
Although we make standard models designed for a variety
of divers and conditions, we can do custom spearguns
for left handed divers or for divers of various sizes.
For example, we can place the handle or trigger mechanism
wherever you like, or we can make a speargun for your
favorite shaft length and diameter. There is rarely
an additional charge for custom work - only if it requires
us to do additional work.
-
If you are visiting this website, you are probably a
diver and so we hope you understand. Manufacturing a
quality hardwood speargun takes quite a lot of time
- approximately 36 hours just to make one unfinished
Delrin speargun. We are divers who have regular full-time
jobs during the week and we can only make spearguns
on the weekends as a side-line. During the diving season
(May through October), we spend most of our weekends
diving rather than making spearguns. During the off
season (November through April), we make-up inventory
of our most popular speargun models. We can make you
a custom speargun (to your dimensions) during the off
season, but during the diving season, we are only able
to sell the inventory we made during the previous off
season. Send email or call to find out what we have
in inventory closest to what you want. All other products
we provide are available all year round. We can also
do smaller jobs like mounting reels, side-stocks, muzzle
stablizers, and gun balancing year round.

Partial Speargun Kits
-
Many spearos want to make a high-quality speargun, but
they lack the expensive machines and tools required
to do it. We take a precision straightened speagun block,
and insert and pin the Delrin, machine the enclosed
track into the Delrin, and install our trigger mechanism
and that part is completely assembled. You do the rest
or you can have us do a few more add-on services listed
below under Services. A Partial
Speargun Kit includes only the gun block, the Delrin
rod, the stainless steel pins, and our trigger mechanism
and it is all assembled. It does not include any other
parts such as the handle, trigger slide, spear shaft,
power bands, or any parts other than those just described,
but it is a good start on making an enclosed track Delrin
gun. Add $50 if you want a laminated block for your
kit.

DIY - Make your own slip tips
Ballasted, Balanced Side Stocks
-
Ballasted, balanced side stocks will reduce recoil (thus
increasing accuracy) and add distance to your effective
shot (because less energy is lost to recoil).
-
All side stocks are made from hardwood and are balanced
with lead to add ballast to and reduce recoil of a speargun
that is too light.
-
All are designed for comfort while diving and loading.
-
Any of these side stocks may be added to the Alexander
Magnum, Blue Water, and Tuna guns to eliminate the high
recoil of these otherwise excellent spearguns. For these
models we recommend at least the Small for the Magnum,
the Medium for the Blue Water, and the Large for the
Tuna gun. You can step-up a size for even more reduction
in recoil. On some spearguns, we may have to relocate
your quick release bracket to the top-side (or under-side
if you prefer) of the side stock.
-
We can also make custom side stocks for almost any hardwood
speargun. We recommend against using full-length "wings"
because they will act like airplane wings underwater
reducing manuverability of your speargun to the point
of making it too difficult to track a fish. Rear-mounted
side stocks do not cause any noticeable reduction in
manuverability.
-
Our side-stocks are neutrally balanced so they won't
change the balance characteristics of your speargun.
We will mount and custom balance our side stocks to
your speargun/shaft/tip combination for an extra fee
of $50. This will correct any pre-existing balance problem,
but some guns may require muzzle stablizers to achieve
proper balance.
-
All side stocks come with attached butt pads which also
help reduce the discomfort some divers feel from the
butt pressing into your chest or thigh while loading
by increasing the surface area of the speargun butt.
-
Our side stocks come with two stainless through-bolts
that thread into stainless nuts embedded on the other
side. All side stocks are finished.

Muzzles
& Muzzle Stabelizers
-
The band slot has been a traditional weak point in the
wooden speargun. The material removed to make the slot
detracts from the strength and stability of the gun
itself. The more bands you want to put on the gun -
the longer the band slot becomes and the more you weaken
the front of the gun. The band slot also puts the bands
out of line with the shaft and end up giving the gun
the 'muzzle flip' that detracts from accuracy as well.
Based on the multitude of problems associated with a
band slot and after many conversations with Ron Mullins
and after the concept gun built by Steve Kang. We now
offer a stainless steel muzzle that can handle up to
9 bands - it is very easy for the home gun builder to
install and it adds strength and stability to the front
of the gun instead of detracting from it. This new muzzle
puts the bands directly in line with the shaft so it
also does the job that front stabelizers do on a band
slot d gun. Lastly you can now put the front line wrap
all the way to the front of the gun instead of behind
the band slot - thus giving the gun addition shooting
line length. Here are some pics of this new design
top view. and here it is installed
on a gun
-
Stainless muzzle pair: $65
-
We also offer muzzle stabilizers which attach to the
muzzle just behind the band slot. They do two things:
1) they move the bands upward so they are in-line with
the shaft and 2) they are ballasted to give the muzzle
more inertia. They help stabilize the speargun muzzle.
We recommend adding both side stocks and the muzzle
stabilizers for maximum stability and accuracy. We add
both to all our personal spearguns and to all our Deluxe
model spearguns.
-
Small Muzzle Stabilizers (up to 4 power bands): $125.
-
Large Muzzle Stabilizers (5 or more power bands): $150.
Top view. Side

-
Complete package: if you get side stocks and muzzle
stabilizers we will include mounting and full speargun
balancing for no extra charge. Or if you order side
stocks and/or muzzle stablizers with your new speargun
order there is no extra charge for mounting and full
speargun balancing as long as you specify that you want
them before we balance your speargun.
Float Lines
-
Bungie floatlines are the way to go for larger fish,
but rigid vinyl float lines work fine for medium to
smaller fish and they are less expensive.
Vinyl Float Lines
-
All vinyl float lines have quick attachments and swivels
at both ends. They are made from clear vinyl tubing
with tuna cord running through the center connecting
the swivel end-plugs. The tuna cord is double crimped
at each end and the ends are sealed with silicone sealant
and firmly attached to the tubing. Picture of a 5/16"
by 65' float line

Bungie
Float Lines
-
Bungie float lines are credited to Ben Wolfe (a Fathomier)
who pioneered the concept with Norprene as the bungie
material. Norprene has a problem though. It is good
for the first big run of the fish, but it has memory
and stayes stretched out, so for the second run of large
fish, it will not provide nearly as much tension on
the fish.
-
Ron Mullins developed a bungie material especially formulated
for tuna bungies. It is a superior elastomer material
which has an extreme high modulous to fight the fish
and a fast rebound to solve the second run problem observed
in Norprene. This stuff just doesn't give up fighting
the fish!
-
9/16" diameter Ron Mullins inspired 3-sigma bungee float
line with 2.2 times length of 1000lb urethane coated
spectra 1000 cord inside connecting the end-plugs. This
is the special formulation - edge of the envelope -
bungee material that has proven time and time again
to be capable of landing even the largest tuna and bill
fish. This material has maximal rebound for run after
run of even the most powerful large tuna. You can see
video of this material fighting big tuna in Mullin's
tuna videos. This special formulation has extreme crosslinking
to give a modulus much higher than is observed in commercially
available rubber. The material will exhibit approximately
200 lbs of force when stretched double its resting length
- total strength with internal spectra shock cord is
over 1000 lbs. It is fortunate that it is also less
expensive than Norprene (which is used primarily in
peristaltic pumps for medical uses).
-

-
1/2" diameter Norprene bungie float line with 3 times
length of 1000lb urethane coated spectra 1000 cord inside
connecting the end-plugs to limit the stretch. Approximately
1200 lb test. You can use fairly large floats (or even
a Kayak or small boat) with these bungies. We recommend
you use the 5/32" forged anchor shackles at each end
to attach to your float and to your shooting line (See
Speargun Rigging below).

Big-Game Floats
-
Our big-game surf board floats are designed for use
with a bungie for deep-diving big-game fish like tuna,
wahoo, and bill fish.
-
Deluxe big-game float, made from Divinycell H60 foam
core - an ultra light, ultra high-density, closed cell
foam core which doesn't absorb water or crush under
pressure - even under 200 feet of salt water. Core is
hand-laminated with fiberglass cloth and polyester resin
to provide a tough outer shell around the foam. Comes
with a highly-visible yellow gelcoat top-coat - the
same color used for lifeguard rescue boats. Dimensions
are 16" wide by 4" thick by 36" long. The low profile
and extremely light weight make it easy to tow while
diving. Provides approximately 70 lbs of flotation --
more than enough for any blue water fish. Includes a
red flag for increased visibility at a distance and
a butt pad to reduce scratching, a front harness for
float line attachment, tail harness for chaining another
float line, and quick clip to aid in fighting fish:

etc) as you plan to use it before balancing. Any change
you make to your speargun may change the balance,
so for example, if you intend to use a reel, you must
mount (or have us mount) the reel before balancing.
We will re-balance any speargun we have previously
balanced (to adjust for small changes like addition
of a reel or change of spear tip for example) for
$25. DIY - ballasting

Free Trial Demonstrations
-
If you treat us to a day of boat diving (preferably
on your own boat) to an area with clear blue ocean
water and game fish (such as the Channel Islands off
the coast of California), we will bring a few of our
speargun models (of your choice) for you to try for
yourself. You may use them all day if you like so
you can evaluate the quality of our spearguns. Compare
them side-by-side to any other speargun made in the
world. We are confident that once you try one of our
spearguns you will know they are by far the best available.
We will provide our own transportation (even airfare
if necessary) to your boat. Southern California diving
is easiest for us, but we may be willing to travel
elsewhere if you can provide a place for us to stay
for a few days. You are under no obligation to buy
a speargun and you can do the free trial even if you
have no interest in getting one. We will be happy
just to dive.
All prices are in US dollars and are subject to change
without notice.
Federal law requires collection of a 10% excise tax on
spearguns and parts.
8.75% sales tax must be added for orders from California
residents.
Ask about cash discounts.
Packing and UPS shipping are available at cost.
Packing and UPS ground shipping a speargun within the
Continental US is approx. $55 because it is over-sized.
Packing and air shipping to Oahu is approx. $75.
